Abstract: Anchored on anitism, this study explains the significant contributions of indigenous knowledge from the plain, mountain range, and selected coastal areas of the Philippines to promote sustainable development. Challenges and interventions in preserving IKSP were also discussed in the study. It was done through careful analysis of relevant literature with the aid of unstructured interview. The study revealed that local knowledge and practices relevant to indigenous belief systems contribute to climate change adaptation and preservation of the natural environment. Besides that, concerted efforts among the academe, government, and indigenous cultural communities (ICCs) on issues and challenges surrounding the preservation of natural resources and IKSPs were found to be more effective and beneficial in policy formulation and project management.
